An informative, useful email signature block, please

The paper letter has all but disappeared from the recruiting process, making it more important than ever that your recruiting email signature block be useful, informative and professional.  Why? 

1.  Readers will make judgments about the content.  Jokes for your pals belong in your "For my pals" signature block.

2.  People may want to pick  up the phone and call you -- shocking, I know. But, without your phone number below your name, the phone call may never come because your caller was distracted.

3.  And, of course, your email address should be professional.  yourname@yourschool.edu or your name@gmail are both fine.  Anything that was amusing when you were in high school should be banished to "Email for my pals," and your high school pals, at that.

My signature block from work is nothing if not informative (name, title, address, phone, fax, email, school blog, Symplicity links for on and off campus interviews, Alumni Student Connection, and, in season, a link to the University of Minnesota Law School's Theater of the Relatively Talentless [T.O.RT.]).
